Art Discovery Group Catalogue is an open-access discovery tool developed by an international network of sixty art libraries and powered by OCLC’s WorldCat search engine. Users worldwide can search aggregated bibliographic data from the participating library’s holdings plus an OCLC metadata pool derived from thousands of commercial and freely-accessible collections, portals, and repositories. This session comprises a demonstration of Art Discovery Group Catalogue and discussion about its ongoing development, and a brief introduction to the library of the Musée des Beaux-Arts de Lyon.
